Definitions

  • the invention relates to an emergency and / or safety lighting system with at least one light, in particular emergency and / or safety light, which has at least one light source for emitting an optically, in particular visually, detectable blinking pattern, and with a device for optically detecting the blinking pattern, wherein the device has an optoelectronic device with a photodetector and with an objective.
  • a device for optical detection of the blinking pattern namely a mobile phone ( WO2017 / 138029A1 ).
  • the light emits a flashing pattern that is recorded by the cell phone's camera.
  • a camera usually has CCD sensors or CMOS sensors as photodetectors as optoelectronic devices, which can, however, disadvantageously become saturated by ambient light when optically detecting a blinking pattern from a comparatively distant lamp.
  • sensors are provided with a comparatively high image resolution, which is advantageous for a depth of field, but makes it difficult to isolate a lamp emitting blinking patterns from a background.
  • the invention has therefore set itself the task of modifying a device for optically detecting a blinking pattern in such a way that the blinking pattern of the luminaire can be steadily detected with it - regardless of the position of a light of an emergency and / or safety lighting system.
  • the device should be particularly easy to use.
  • the invention solves the problem posed by the features of claim 1.
  • the device can be made particularly robust with respect to ambient light when a blinking pattern is to be optically detected by a lamp.
  • the photodiode as a light sensor can also be distinguished by a comparatively favorable time behavior - which counteracts sensor saturation due to flicker and / or flicker of other lighting means. This is particularly advantageous when detecting luminaires that are spatially further away, where more ambient light is to be expected when their blinking patterns are optically detected.
  • a flashing pattern of a lamp of an emergency and / or safety lighting system can thus be reliably optically detected, in particular regardless of its position, which can also facilitate the handling of the device.
  • the stability in the optical detection of the blink pattern can be increased if the photodiode has a sensor area of 4 to 9 mm 2 , in particular 2.73 ⁇ 2.73 mm.
  • the lens is preferably designed as a telephoto lens in order to restrict the optical detection of ambient light - which can be the case in particular with lamps that are comparatively far away.
  • the optoelectronic device has an angle of view in the range from 0.6 to 28 degrees in order to be able to robustly detect flashing patterns of differently arranged lights of an emergency and / or safety lighting system.
  • an angle of view in the range from 4 to 7 degrees, preferably 5.7 degrees leads to a device that is improved in terms of ease of use for a distance-independent detection of a blinking pattern.
  • the entry of ambient light can be further reduced if the optoelectronic device has a lens hood upstream of the lens. This further increases the stability of the device.
  • the detection of a flashing pattern - even with lights that are comparatively far away - can be further facilitated if the device has a laser beam source whose laser beam is inclined towards the optical axis of the lens.
  • Constructive simplicity can be achieved if the device has a tube that receives the photodetector and the lens and forms the lens hood. Furthermore, the robustness of the device can thus be further increased.
  • the inside of the tube is preferably colored black in order to reduce reflections on the optoelectronic device and to further increase the stability of the device.
  • the handling of the device is further facilitated.
  • the handle part preferably has a battery for the electrical supply of the device in order, for example, to ensure a long service life when detecting blinking patterns.
  • the objective can have a converging lens, in particular held in the tube, the focal point of which lies on the sensor surface of the photodetector, in order to ensure a comparatively high sensitivity of the device when detecting a blinking pattern.
  • the device preferably has a vibration element for haptic confirmation of the blinking pattern detected by the device in order to further improve the handling of the device.
  • the flashing patterns of the at least two lights of the emergency and / or safety lighting system preferably differ from one another. This means that the flashing pattern of the respective lamp is clear, which can facilitate optical detection by the device.
  • the emergency and / or safety lighting system preferably has a control center, the lamp and / or the device being connected to the control center.
  • a wireless and / or wired data connection can be particularly suitable for this purpose.
  • FIG. 1 shows an emergency and safety lighting system 1 (or emergency lighting and safety lighting system) with several, in the exemplary embodiment two, lights 2a, 2b, namely emergency and safety lights, and with a device 3 for optical, visual detection of a flashing pattern 4a, 4b.
  • emergency and safety lighting system 1 or emergency lighting and safety lighting system
  • This flashing pattern 4a, 4b is emitted by the emergency and safety lights 2a, 2b.
  • the respective flashing patterns 4a, 4b of the lights 2a, 2b can differ from one another. It is therefore clear what a simultaneous output of the flashing patterns 4a, 4b can enable, for example during the initialization of an emergency and / or safety lighting system 1.
  • the lights 2a, 2b are for example connected to a control center 7 of the emergency and / or safety lighting system 1 via a wired data connection 6.
  • the lights 2a, 2b have lighting means 5a, 5b, for example in the form of at least one LED.
  • These illuminants 5a, 5b are preferably used to illuminate or backlight a display 8a, 8b of the lamps 2a, 2b and / or to illuminate escape routes.
  • the device 3 for optically detecting a blinking pattern 4a of the blinking patterns 4a, 4b has an optoelectronic device 9 with a photodetector 10 and with an objective 11.
  • the ambient light scattering during the optical detection of the flashing pattern 4a of the lamp 2a which can also include a flashing pattern 4b of another lamp 2b, natural sunlight, flickering and / or flickering and / or flickering of other lamps, not shown, etc., can be made by the device 3 does not impair its function, because according to the invention it has a photodiode 10a in the form of a component, namely a PIN photodiode ("positive intrinsic negative diode”), as photodetector 10 - as in FIG Fig. 2 in particular to recognize.
  • the sensor area is 4 to 9 mm 2 (square millimeters), namely 2.73 x 2.73 mm (millimeters), which ensures sufficient sensitivity when detecting the blinking pattern 4a of the lamp 2a.
  • the lens 11 is designed as a telephoto lens with a converging lens 11b, the optoelectronic device 9 having an image angle ⁇ in the special range of 4 to 7 degrees, namely exactly 5.7 degrees, as in FIG Fig. 2 to recognize. In this way, a blink pattern 4b of a lamp 2b that is comparatively high or far away can easily be optically detected by the device 3.
  • the optoelectronic device 9 also has a lens hood 12 connected upstream of the lens 11 in order to further reduce the proportion of undesired ambient light.
  • the device 3 In order to be able to aim at the respective lamp 2a, 2b in a manageable manner from the device 3, the device 3 is provided with a laser beam source 13, the laser beam 13a of which is inclined towards the optical axis 11b of the objective 11 - as in FIG Fig. 1 and Fig. 2 to recognize.
  • the device 3 has a tube 14 which receives the photodetector 10 and the objective 11 and also forms the lens hood 12, in which the tube 14 protrudes further from the objective 11.
  • the inside 14a of the tube 14 is colored black, which further reduces unwanted ambient light captured by the optoelectronic device 9.
  • the device 3 also has a handle part 15 to which the tube 14 is connected at an angle with respect to the longitudinal axis 15a of the handle part 15.
  • a battery 16 for the electrical supply of the device 3 and also a computing device 17 at least for evaluating the sensor data of the photodiode 10a are provided in the handle part 15.
  • the focal point of the converging lens 11a preferably coincides with the photodetector 10 or the focal point is located on the photosensitive surface of the photodetector 10.
  • the device 3 has a vibration element 18 for haptic confirmation of the blinking pattern 4a, 4b successfully detected by the device 3.
  • the respective lamp 2a, 2b can also be identified via the unidirectional flashing pattern 4a, 4b, for example during the initialization of the emergency and / or safety lighting system 1.
  • the lights 2a, 2b can, however, also be designed, for example, as single-battery lights, that is to say without a wired data connection 6.
  • the device 3 has a radio module 19 which can communicate, for example, with a light radio module (not shown in detail) of the lights 2a, 2b.
  • the radio module 19 can also communicate with, in particular mobile, terminals (not shown) and / or with the control center 7. The device 3 can thus transmit the data received via the flashing pattern to the terminal device and / or to the control center 7.
  • the radio module 19 can be used to communicate bidirectionally with the lamp 2a, 2b and / or the control center 7.
